Common Mistakes to Avoid When Sealing Asphalt

Asphalt sealing is a crucial step in preserving the longevity and appearance of your driveways and parking lots. When done correctly, it can protect your asphalt from the elements, prevent cracks, and extend its lifespan. However, many people make common mistakes when sealing their asphalt that can lead to subpar results or even damage. In this blog, we’ll highlight some of these frequent errors and provide guidance on how to avoid them.

1. Skipping Proper Preparation

Mistake: One of the most common mistakes is neglecting proper preparation. Some people skip cleaning and repairing their asphalt before applying sealant. This can result in poor adhesion and a shorter lifespan for the sealcoat.

Solution: Before sealing, thoroughly clean the surface of dirt, debris, and oil stains. Fill cracks and potholes with appropriate materials, ensuring a smooth and even surface.

2. Ignoring Weather Conditions

Mistake: Sealing your asphalt during unfavorable weather conditions, such as rain or extreme heat, can lead to a suboptimal seal. The sealant may not adhere correctly or may not cure properly.

Solution: Check the weather forecast and choose a day with dry and moderate temperatures for sealing. Ideally, the temperature should be above 50°F (10°C) and no rain should be expected for at least 24-48 hours after application.

3. Applying Too Much Sealant

Mistake: Over-application of sealant is a common error. A thicker layer doesn’t necessarily provide better protection and can result in a sticky, uneven surface.

Solution: Follow the manufacturer’s recommendations regarding the proper coverage rate for the sealant. Typically, one or two thin coats are sufficient. Use a squeegee or spray application for even distribution.

4. Rushing the Process

Mistake: Rushing through the sealing process can lead to uneven application and a subpar finish. Some people try to complete the job too quickly, especially when working on larger areas.

Solution: Take your time and work methodically. Ensure that you maintain a consistent pace during application to achieve a uniform coating. Pay attention to detail, especially around edges and corners.

5. Neglecting Edge Sealing

Mistake: Many people forget to seal the edges of their asphalt surfaces, focusing solely on the central area. Neglecting the edges leaves them vulnerable to moisture infiltration and premature deterioration.

Solution: Apply sealant to the edges of the asphalt as well, using a small brush or specialized edge sealer. This will create a watertight barrier around the entire surface.

6. Applying Sealant Too Often

Mistake: While sealcoating is essential, applying it too frequently can lead to a buildup of layers that can crack and flake over time.

Solution: Stick to a recommended sealing schedule. Typically, you should reseal your asphalt every 2-5 years, depending on the level of wear and tear.

7. Choosing the Wrong Sealant

Mistake: Selecting the wrong type of sealant for your specific asphalt surface can lead to ineffective protection and wasted effort.

Solution: Understand the different types of sealants available, such as coal tar, asphalt emulsion, or acrylic-based sealers, and choose the one that best suits your needs and climate conditions.

8. Lack of Safety Precautions

Mistake: Some people overlook safety precautions, such as wearing protective gear and ensuring proper ventilation when applying sealant, which can pose health risks.

Solution: Always wear appropriate protective clothing, including gloves and a mask. Ensure good ventilation during application, especially in enclosed spaces.

If you avoid these common mistakes when sealing your asphalt, you can make a significant difference in the quality and longevity of the results. By taking the time to prepare, selecting the right conditions, and applying the sealant correctly, you can enjoy a well-protected and aesthetically pleasing asphalt surface for years to come. Proper asphalt sealing and maintenance will not only enhance the appearance of your property but also save you money in the long run by preventing costly repairs.
